There are two updates for WebObjects — WebObjects 5 Developer and WebObjects 5 Deployment — you do not need both updates on any system, according to Apple. WebObjects 5 Developer Update 1 requires Mac OS X 10.0.4 or later and WebObjects 5 Deployment Update 1 requires Mac OS X Server 10.0.4.
Apple also notes that you must be logged in as the “root” user in order to perform the installation. Logging in as “Administrator,” or authenticating as “root” is not sufficient to complete the update. You must also ensure that no WebObjects or EOF applications are running during the installation of the update.
download the WebObjects updates from Apple’s download site. Alternately you can use the Software Update control panel — using this method, only the proper update for the software that you have installed on your system will be visible and available for download.
